[PATCH] bonding: Fix link monitor capability check (was skge: set mac address oops...

Fix bond_enslave link monitoring warning to check use_carrier status
and ethtool_ops in addition to do_ioctl.  This version checks ethtool_ops
as well as do_ioctl, and also uses the per-bond params.use_carrier
instead of the global use_carrier.
